Question

During a head-on collision between two automobiles, the occupants are decelerated rapidly. Use the idea of work to explain why an air bag that quickly inflates in front of an occupant reduces the likelihood of injury
a.The air bag expands as the person's body is thrown forward, so the same force acts over a smaller distance compared to the person hitting the steering wheel or dash.
b. The air bag compresses as the person's body presses against it, so a smaller force acts over a longer distance compared to the person hitting the steering wheel or dash.
c. The force is spread over a smaller area, and so the force is smaller for the same amount of pressure.
d. The force is spread over a larger area and the pressure is smaller
